Sunday, September 13, 2026 | 3:25 p.m. CT | Allegiant Stadium, Las Vegas | FOX
DraftKings (Aug. 31): LV -3.5 | Over/under: 40.5
Opening numbers: LV -3 | Opening over/under: 41.5 (lines move) [S1/S3]

The setup

Both teams changed the face of the offense. Miami paid Malik Willis and released Tua Tagovailoa; Las Vegas will open with veteran Kirk Cousins while No. 1 pick Fernando Mendoza develops behind him.

What I’m watching

Is Willis' tiny but electric 2025 passing sample portable to a full game plan, and can Cousins stabilize an offense playing behind a line that finished last in sack rate allowed?

Personnel snapshot

• The roster note: Malik Willis begins Miami's post-Tua era. Kirk Cousins starts for Las Vegas, with No. 1 pick Fernando Mendoza waiting behind the 15th-year veteran.
• The current hook: The quarterback reset is total: Miami gave Malik Willis three years and $67.5 million, while Las Vegas chose 15th-year veteran Kirk Cousins over No. 1 pick Fernando Mendoza for the opener. [S13]
• The game-shaping angle: De'Von Achane became just the fifth running back since 2000 with 10-plus scrimmage touchdowns in each of his first three seasons. He had 105 yards and a touchdown in his last meeting with Las Vegas. [S14]

Three quick analysis points

• The numbers clash: The Raiders ranked last in offensive EPA per play and averaged 14.2 points. Miami was only 22nd in offensive EPA, so both new quarterbacks inherit real repair work. [S7/S8]
• The leverage point: Here is the fun Willis stat—with a giant sample warning. On seven PFF deep attempts in 2025, he completed all seven for 230 yards and two touchdowns; he threw only 35 passes total. [S6]
• The tell-your-friends stat: Las Vegas ranked last in sack rate allowed, but Miami ranked last in PFF pass-rush grade. One of those weaknesses has to give. [S4/S7]

How the game is decided

The winner is the new-to-his-team quarterback who gets the cleaner pocket. This game is less about ceiling than whether Cousins or Willis can avoid the structural problems both offenses carried into 2026.
